Title: Sterile rinsing appts. for dental operations - uses unsterile device to expel sterile fluid from flexible bulb
Inventor: BAUMANN RALPH R DR DR MED
IPC: A61C1/00
Filed: 1976-04-06
Abstract: A sterile rinsing fluid is to be held in a flexible bulb (P) placed inside a rigid tube (3). Water (through U) from the unsterile apparatus is used to fill the space between bulb and tube, and the air-inlet valve (V) is then closed. From then on, water pumped into the tube from the unsterile rinser expels an equal quantity of sterile rinsing fluid from the bulb. The appts. replaces a known rinsing apparatus, operated by the dentist himself, and thought not to give a sufficiently sterile rinse, and which itself has been replaced by an inconvenient procedure requiring the help of an assistant.

Title: Heat accumulator based on the latent heat of fusion - using a fluid heat carrier to bring and remove the heat
IPC: F28D20/02
Filed: 1977-10-10
Abstract: Process for heating and removing the heat from a substance capable of accumulating latent heat by means of a fluid heat carrier comprises passing. The heat carrier through the substance from the bottom to the top and is collecting it at the top surface. The carrier is immiscible with the heat accumulating substance-usually a salt. The carrier is fed into the salt in a direction and by an inlet section such that horizontal flow components are set up and in the molten mass of the salt and a gyratory-movement is imparted to the mass. The reservoir contg. the salt is cylindrical with a vertical axis. The pipe bringing the heat carrier has >=1 outlet situated to one side of the axis of the cylinder and orientated horizontally and nearly perpendicular to the radius of the cylinder. Latent heat accumulators enable large quantities of heat to be stored in a relatively small volume. The appts. reduces foam formation on top of the salt which would tend to damage the pump. It also improves the heat exchange at the start of the heating and at the end of the heat removal processes.
